Yeah I doubt it. I’ve worked in large Rust codebases too. I’d do some benchmarking. Cargo has some nice flags that let you see exactly what it’s doing. You can open the compilation report up in a browser and zoom in on different steps of the process and see everything.

That’s highly abnormal to have minute long debug build times.

Five minutes with build cache? Or from cold build?

With cache, then there’s almost certainly something wrong with your computer or project.

Also… you aren’t building with --release every time are you?

I find Rust extremely fun

IDK, I’d think the best path forward would be to just fork Android and move on from there. That’s what Graphene OS already does. Just standardize on Graphene OS for everything and get them more devs / resources.
